Unauthorized Housing Companies Contacting Exhibitors & Attendees

It has come to our attention that unauthorized housing companies have been contacting National Hydropower Association Annual Conference, IMREC and METS sponsors, tabletop participants and attendees via email and phone and in general, misrepresenting themselves as an official housing vendor for the National Hydropower Association Conference, International Marine Renewable Energy Conference (IMREC) and Marine Energy Technology Symposium (METS).

The only official housing for the three co-located events is through Capital Hilton.  All other companies do not have any affiliation with National Hydropower Association, IMREC or METS.  We highly caution you from engaging unauthorized companies because if/when issues arise, National Hydropower Association, IMREC and METS management do not have the ability to provide assistance in solving them. 

Please report any unauthorized housing and travel solicitations to Lisa Gasaway at lgasaway@pennwell.com.
